Sandberg offer a comprehensive site Ground Penetrating Radar survey service, including off-site data processing, analysis, interpretation and reporting.

What is Ground Penetrating Radar?

Ground Penetrating Radar (also known as Ground Radar, Ground Probing Radar, Georadar, GPR and Surface Penetrating Radar) provides a non-intrusive and non-destructive method of surveying the Subsurface, including Concrete Imaging. It is a highly cost effective non-intrusive (ND) technique, offering a rapid means of obtaining subsurface information from a variety of materials used in the construction industry including concrete, brick, masonry, wood, asphalt and soil.

Ground Penetrating Radar is a geophysical technique originally developed for mapping geological features, but it is now increasingly used for Civil Engineering applications. Sandberg specialise in the use of GPR in the Construction Industry including, but not limited to:

  • Concrete imaging and rebar detection
  • Concrete floor slab surveys
  • Chimney flue location
  • Historical building characterization (incl. embedded steel location)
  • Locating tendon ducts
  • Locating under floor heating pipes
  • Retaining wall surveys
  • Structural investigation surveys
  • Wall and slab thickness measurement
  • Shallow foundation and pile-cap location
  • Railway ballast thickness and evaluation
  • Grave and crypt location
  • Voids in construction and below slabs

NDT

GPR can determine sub-surface detail, rebar distribution, voids, etc. non-intrusively without damage to the surrounding structure.

Speed and Efficiency

GPR scanning is quick and efficient and is suitable for scanning large or small areas. If required, preliminary results are available in real time.

Limit Risk

GPR can help limit exposure and control risk by locating potential problems and confirming compliance with specification.

Featured GPR Surveys

GPR is a flexible NDT survey technique suitable for many different applications.
